Dh10-Beta Competent E. coli

Description:
The DH10B competent E. coli has a transformation efficiency of 1 x 10⁹ cfu/µg for supercoiled DNA and is ideal for high-efficiency cloning and plasmid propagation. It enables stable replications of high-copy number plasmids. In comparison with DH5a, methylated DNA from genomic preparation could be efficiently transformed into DH10B, therefor DH10B cells are more applicable than DH5a in generating genomic libraries containing methylated cytosine or adenine residues.

Application:

• Highest transformation efficiency
• General cloning
• Blue-white selection
• Reduced recombination of cloned DNA (recA1)
